Introduction
Thanks for choosing an Omega device.
DP400S is an indicator/panel meter for acquisition and retransmission of
processes, also with fast transient. It is provided with relay outputs for
alarm purpose, analog output for retransmission ofprocess/setpoints and
programmable digital inputs.
Available in standard format 96 x 48 mm, the device can be configured both for
horizontal and vertical mounting.
Distinctive feature is the intuitive multilingual interface, supported by a graphic
OLED monochromatic yellow display 128 x 64 pixel.
Visualization options include bar graph and process trend with programmable
sampling time.
Software features include mathematical functions related to process value like
totalizer andsum.
Serial connectivity relies on RS485 and Modbus-RTU protocol.
Safety guide lines
Read carefully the safety guidelines and programming instructions contained in
this manual before using/connecting the device. Disconnect power supply
before proceeding to hardware settings or electrical wirings.
Only qualified personnel should be allowed to use the device and/or service it
and in accordance to technical data and environmental conditions listed in this
manual. Do not dispose electric tools together with household waste material.
In observance European Directive 2002/96/EC on waste electrical and electronic
equipment andits implementation inaccordance with national law, electric
tools that have reached the end of their life must be collected separately and
returned toanenvironmentally compatible recycling facility.

5 Electrical wirings
Although this controller has been designed to resist noises in an industrial
environment, please notice the following safety guidelines:
• Separate control lines from the power wires.
• Avoid the proximity of remote control switches, electromagnetic meters,
powerful engines.
• Avoid the proximity of power groups, especially those with phase control.
For permanently connected equipment:
• supply wiring must be ≥18 AWG with cables suitable for temperatures > 70° C;
• for requirements about any external switch or circuit-breaker see EN 61010-1
par. 6.11.3.1 and about external overcurrent protection devices see EN
61010-1 par. 9.6.2; the switch or circuit-breaker must be near the equipment.
